Replaced the use of a Variable Length Array In Struct (VLAIS) with a C99
compliant equivalent. This patch allocates the appropriate amount of memory
using a char array using the SHASH_DESC_ON_STACK macro.The new code can be compiled with both gcc and clang.

Move the support to perform an HMAC calculation into
the CCP operations file. This eliminates the need to
perform a synchronous SHA operation used to calculate
the HMAC.Signed-off-by: Tom Lendacky

Cleanup the ahash digest invocations to check the init

When performing a hash operation if the amount of data buffered and a
request at or near the maximum data length is received then the length
calcuation could wrap causing an error in executing the hash operation.
Fix this by using a u64 type for the input and output data lengths in
all CCP operations.Signed-off-by: Tom Lendacky

been supplied.Signed-off-by: Tom Lendacky
